The Visual Analytics gallery highlights dashboard projects where the main challenge was not only building visuals, but preparing data into the right structure, selecting effective encodings, and designing interactive views that answer focused analytical and business questions across Tableau and Power BI.

Data Preparation Cleaned, reshaped, pivoted, joined, and transformed data for dashboard-ready analysis.

Visual Design Used maps, bar charts, heatmaps, dumbbell charts, line charts, and dashboard layouts.

Interactivity Added filters, tooltips, parameters, and calculated fields to support user-driven exploration.
